Nissan’s powertrain warranty covers the 370Z 1 year and 10,000 miles longer than Audi covers the A5. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the A5 ends after only 4 years or 50,000 miles.

There are almost 4 times as many Nissan dealers as there are Audi dealers, which makes it much easier should you ever need service under the 370Z’s warranty.

To reliably power the ignition and other systems and to recharge the battery, the 370Z has a 150-amp alternator. The A5’s standard 110-amp alternator isn’t as powerful.

J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Nissan vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Nissan 7th in initial quality, above the industry average. With 20 more problems per 100 vehicles, Audi is ranked 22nd, below the industry average.

If the windows are left open on the 370Z the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. The driver of the A5 can’t use the remote to operate the windows.

According to The Car Book by Jack Gillis, the 370Z is less expensive to operate than the A5 because it costs $388 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the 370Z than the A5, including $66 less for a water pump, $226 less for a muffler, $59 less for front brake pads, $215 less for a starter, $4 less for fuel injection and $15 less for a fuel pump.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Nissan 370Z will be $1530 to $7997 less than for the Audi A5.
